I think this is a very interesting question.

I'm leaning towards saying that *in this particular case* it may make
more sense to allow unprefixed implementations (of 'zoom-in' and
'zoom-out') rather than encourage implementations to only support
vendor-prefixed versions.

However that's just my opinion and is a larger matter that the working
group needs to consider.

There is very little "official" guidance on vendor prefixes - you're not alone.

There was a flurry of email list and telcon and f2f discussion
activity around vendor-prefixes and yet I can't find *any* summary of
conclusions / current state of guidance on vendor-prefixes (insert the
I hate email and it's lack of community memory, inaccessibility,
unsearchability problems).

So instead, I've written this up on our wiki:

Please take a look and feel free to edit, add your opinions,
additional open questions etc.

Multiple opinions appreciated - let's capture the diversity and figure
out best paths forward. EXCEPT, not in email. We already plenty of
that (search last year's www-style archives), and nothing persistent
came out of it.

Just edit the wiki.

I've added the specific case of cursor:zoom-in and zoom-out for consideration.
